Crystal hydrates of alkali metal isopolyvanadate molybdates or tungstates as thermosensitive resistor materials or catalysts of trimethylphenol oxidation and method of their preparation

Description

Crystal hydrates of alkali metal isopolyvanadate molybdates or tungstates of the Msub(2)Vsub(12-y)Ehsub(y)Osub(z)xnHsub(2)O composition (M-alkali metal; Eh-Mo or W; 0.5 <y <= 4; 31 <= z <= 33) are prepared by V(S) oxide interaction with the solution containing alkali metal molybdate or tungstate in the stoichiometric relation to V and to 200 g/l hydrogen peroxide at 1-10 deg C for 0.5-1 hour, the following heating of the reacting mass to 60-80 deg C, holding for 0.5-1 hour at this temperature and drying of the product at normal or high temperature. Compounds with 1 <= y <= 3 and 31.5 <= z <= 32.5 are recommended as catalysts
